Part Description
The LM3102/-Q1 SIMPLE SWTCHER® Synchronously Rectified Buck Converter features all required functions to implement a highly efficient and cost-effective buck regulator. The device can supply 2.5 A to loads with an output voltage as low as 0.8 V. Dual N-channel synchronous MOSFET switches allow a low component count, thus reducing complexity and minimizing board size. Different from most other COT regulators, the LM3102/-Q1 does not rely on output capacitor ESR for stability, and is designed to work exceptionally well with ceramic and other very low-ESR output capacitors. The device requires no loop compensation, results in a fast load transient response and simple circuit implementation. The operating frequency remains nearly constant with line variations due to the inverse relationship between the input voltage and the ON-time. The operating frequency can be externally programmed up to 1 MHz. Protection features include VCC undervoltage lockout (UVLO), output overvoltage protection, thermal shutdown, and gate drive UVLO. The LM3102/-Q1 is available in the thermally enhanced HTSSOP-20 package, and LM3102 is also available in a DSBGA low-profile chip-scale package with reduced output current.
